Abstract: At least one of these digital chips (BA1,...BAi-1, BAi) arranged on a module exhibits at least one tristate-capable output (A'1,... A'i-1, A'i). For this purpose, test signals are applied to the inputs of the chip to be tested and its output signals are recorded and evaluated. The chip to be tested is selected by means of binary control signals to test disconnection inputs which are either accessible directly or via a decoding chip or a serially loadable register with parallel readout. For this purpose, the tristate-capable outputs of the chips not to be tested are switched to high impedance by the binary control signals of one logic state whilst the chip to be tested remains unaffected by a binary control signal of the other logic state. <IMAGE>

Abstract: A switching device (22) responsive to an input voltage V A  is powered by low and high internal supply voltage V L  and V H . The switching device (22) changes state as V A -V L  passes a threshold voltage V T . After the switching device (22) makes a desired change of state in response to rising V A , a hysteresis circuit (24) temporarily decreases V T  below that which would otherwise be present. Likewise, after the switching device (22) makes a desired change of state in the opposite direction when V A  is falling, the dynamic hysteresis circuit (24) temporarily decreases V T . In both cases, V T  later automatically returns to its original value. This dynamic hysteresis prevents spikes in V L  and V H  from causing undesired changes in state.

Abstract: Die vorliegende Erfindung betrifft ein Meßverfahren zur Messung und genauen Lokalisierung von Zugeigenspannungen in gehärteten Bereichen von Bauteilen, insbesondere bei Turbinenschaufeln, sowie eine Vorrichtung zur Durchführung dieses Verfahrens. Es werden zunächst in an sich bekannter Weise die Koerzitivfeldstärke (Hc) und die magnetische Barkhausen-Rauschamplitude (Mmax) gemessen. Da jedoch diese beiden Meßwerte jeweils sowohl von der mechanischen Spannung (Sigma) wie auch der Härte (HV) des Bauteiles (1) abhängen, werden diese Meßwerte anhand von gespeicherten Kalibrierdaten, die zuvor an Kalibrierproben des gleichen Werkstoffes ermittelt wurden, umgerechnet in die mechanische Spannung (Sigma) und die Härte (HV). Eine entsprechende Auswerteelektronik (12) ermöglicht on-line die direkte Ermittlung von mechanischen Spannungen (Sigma) und Härte (HV), während ein Erreger-Meßaufnehmersystem (2, 3, 5) einen zu untersuchenden Bereich eines Bauteils (1) abtastet.

Inventor: KATZENSTEIN HENRY S
IPC: H03K17/66
Filed: 1988-07-04
Abstract: First and second switches such as transistors are connected to a charge storage member such as a capacitance. The capacitance is charged through the first transistor from a positive supply when the transistor becomes conductive. The capacitances is discharged through the second transistor to a reference potential such as ground when the second transistor becomes conductive. The conductivities of the first and second transistors are controlled by pulses from a pulse source such as a transformer. The transformer primary produces a pulse of one polarity upon the occurrence of the leading edge of an input signal and a pulse of an opposite polarity upon the occurrence of the trailing edge of the input signal. Two secondary windings are respectively connected in opposite polarities to the bases of the first and second transistors to provide for the conductivity of only one of the transistors at any one time. The transformers saturate the conductive transistor to prolong on a limited basis the time during which the transistor remains conductive. The other one of the transistors is made instantaneously non-conductive by providing for an instantaneous discharge of the stored base charge between the base and emitter of the transistor. A constant current source is electrically in parallel with the first transistor to sustain the capacitance charge at a high level after the limited period of time in which the first transistor remains conductive. A low frequency transistor is connected in parallel with the second transistor to sustain the discharge of the capacitance after the limited   period of time in which the second transistor remains conductive.

Abstract: 2.1 The method is intended to make it possible for control and program structures which are used for controlling multi-stage switching networks in digital telecommunication, particularly telephone exchanges, also to be used in the same manner if only a single time-division/space-division switching stage is present, that is to say a single-stage arrangement exists. Thus, it is intended to avoid that special control procedures and program structures must be specially developed for use with single-stage exchanges. 2.2 In the control device provided for controlling a time-division/ space-division switching stage, additional memories are provided wherein the time slot allocations and connection relations used during the setting up of the connection are stored in the same manner as they would exist in the case of several time-division/space-division switching stages and a higher-level switching stage. From these stored data, the adjustment information items for the circuit switching memories located in the single switching network of the single-stage exchange are obtained and used for controlling the release of the connections. 2.3 The method is used in digital circuit-switching small and medium-sized telecommunication, particularly telephone exchanges. <IMAGE>

Abstract: Integral vanes 4 with optimized size, shape and bend angles maximize coolant mixing and fuel rod 12 heat transfer downstream. Recessed weld nuggets 5 with no vane cutout are optimized for size, strength and corrosion resistance. Staggered arches 20′,22′and springs 20,22 minimize turbulence and reduce grid pressure drop and promote coolant mixing. Crowned arches 20′,22′and springs 20,22 decrease scoring of fuel rods 12 and are sized to minimize turbulence and pressure drop. Minimum cutouts in unslotted section of grid strip 46,46′ give 15-20% strength increase. Intermediate weld and tapered end slots 48 give 15% strength increase. Ribbed and round dimple stiffeners 38,39 on outer strips increase buckling resistance, reduce handling damage and spreads accidental loading. Outer strips 32 are optimized for strength, handling, turbulence generation and pressure drop. They also divert enough flow to interior of fuel assembly to match thermal power distribution and eliminate fuel rod corrosion concerns.

Abstract: Three-dimensional photographs produced with image bands of substantially equal density across the field of the lenticule are produced by increasing the intensity of exposure of the image bands near the edges of the lenticule in relation to the central image bands. This is accomplished by varying the duration of each exposure, or using a neutral density filter, a neutral density iris, a metallic iris with a multiple number of apertures, or by controlling the lamps in a multiple lamp housing. In addition, three-dimensional photographs are produced by a multiple number of successive exposures of short duration through the lenticules of the lenticular print film while the angle of projection of the enlarging lens is constantly changing. Exposure is made for a duration while the relative movement of the enlarging lens with respect to the lenticular print film is less than one-tenth of the aperture of the enlarging lens.
